Concept Search - What can I type?

For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.

Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

Abstract

Figure 1 illustrates a typical configuration for a gradient index lens array imaging system. Array 10, comprising a plurality of fibers 12 is positioned intermediate parallel object and image planes 14 and 16. In the case where the object is not planar, for example, a CRT tube face 18, shown dotted, array 10 is no longer capable of providing the proper image. Figure 2 shows a modified lens arrav 20 wherein each of the fiber lengths 21, 22 have been modified in accordance with the equation:

Figure 1 illustrates a typical configuration for a gradient index lens array imaging system. Array 10, comprising a plurality of fibers 12 is positioned intermediate parallel object and image planes 14 and 16. In the case where the object is not planar, for example, a CRT tube face 18, shown dotted, array 10 is no longer capable of providing the proper image. Figure 2 shows a modified lens arrav 20 wherein each of the fiber lengths 21, 22 have been modified in accordance with the equation:

-2 tan[?)

= L 29+ = TC nVA +L

0

Where L is the fiber length,.Q is the vertex distance, VK is the gradient constant, and no is the axial refractive index.

The final spherical form of the array is made by grindinn and polishing the unper and lower surfaces.
